Update
My cluster is together, and tested. It does need to be disassembled, and have the final plexi face cut. The one that's in there now has had some holes drilled in the wrong place. I also need to install the second ccfl bulb. The inverter I have will only light one bulb brightly. If I connect two bulbs to it, they are quite dim and do not light up the cluster nearly as much as the one bulb in there now. Because of the way I have the "brain board" mounted,
the ribbon cable for the lcd displays was too short. I lengthened it with a modified 40 pin IDE cable from a desktop computer.
The backlights mount to a plexi piece that sits between the lcd's and their circuit board. To help reflect the light forward, I'm reusing the stuff out of a laptop screen. Right now these pieces are just taped in place on the plexi. Once I get a second inverter, there will be one bulb at the top and bottom of the cluster. Right now there is only one in the center, because I was excited to get it together and tested. The bulbs will be fastened with a combination of super hot glue and a couple tiny zip ties.
Here's the back of the assembled cluster, before it was placed in the housing.
It's assembled in this order:
1. Plexi face
2. Craft store black foam
3. LCD displays
4. Backlight panel
5. LCD display circuit board
The displays are fastened with 1/8" stepped metal things used for mounting mirrors on walls, and for "bolting" them in place I used a computer motherboard mounting kit. The only problem with them is that the screws are a little on the short side.The final product will use small nuts and bolts with a tiny bit of thread locker. To keep them spaced apart evenly, I made some small "T" shaped pieces placed in the gaps between the center display and the outer ones.
Here's the cluster unlit, and the plexi face has no tinting on it. I have a bunch of samples from a local tint shop, and once both backlights are installed, I'll be able to see how dark I should go. For trimming the display areas out of the foam, I used an exacto knife and the Cougars cluster face as a guide.
And here it is all lit up.
Again, this is only with one backlight and it's in the center. I'm quite happy with the relocation of the brake, highbeam, and seat belt indicator lamps. The two visible screws in the face will be painted flat black to help blend them in. I'm happy with the way this is now coming along, and I think that aside from tinting the face, this is the closest to stock looking I will be able to achieve. During the final disassemble, reassemble stage I will do the blue tint mod.
One thing that I noticed during testing, that was different from NICE59's test of the displays, is that the coolant gauge icon didn't flash, the oil one did flash, and the amp meter indicated it was charging. So I have to look into the wiring diagrams and see what's up. Also, no matter how I tried to figure out a way to have it, for me there just isn't enough room for the shift indicator. In the spring I will figure out a floor shifter.
